WR series for maximum mixing performance and quality
The latest generation WR series machines from Wirtgen are ideal for a broad spectrum of applications ranging from cold recycling – structural road rehabilitation – to the stabilisation of a wide range of construction materials, e.g., soil stabilisation or consolidation in the construction of traffic infrastructure. The machines impress with optimised operating as well as consistently high productivity and mixing quality. With the new operator’s cabin and an improved operating concept, the WR series machines enable particularly efficient and cost-effective workflows.
The WR series machines are ideal for a broad spectrum of applications ranging from cold recycling to the stabilisation of a wide range of construction materials, e.g., soil stabilisation or consolidation in the construction of traffic infrastructure.
The WR series offers a range of models that fulfill a variety of requirements. For instance, the compact dimensions and low machine weight of the WR 200 X make it very easy to transport from place to place. The WR 240 X strikes a perfect balance between machine performance and weight to assure high daily productivity. The WR 250 X is the most powerful machine of the WR series and provides the highest productivity.
All three models offer working widths of up to 2,400 mm. Depending on the model, the engine power output is between 305 and 571 kW. The improved Duraforce milling and mixing rotor enables consistently high mixing quality and productivity under all working conditions and contributes to the minimization of fuel consumption, CO₂ emissions, and wear.
The most important aspect of the new cold recyclers and stabilisers is their revised and improved operating concept. A new multifunction joystick, fingertip control, and ergonomic height adjustment via the multifunction armrest ensure maximum ease of use. In addition to digital process monitoring, the large screen of the machine control panel offers application-relevant displays and the Wirtgen Group CoPilot. Amongst other things, the CoPilot provides interactive tutorials and a self-training function with animations for familiarisation with the machine and its functions displayed directly on the machine’s control panel.
The self-training tutorials help operators to familiarise themselves with the machine and its functions. Animations displayed on the machine’s control panel quickly enable the operator to exploit the full potential of the machine. Explanations of the steering modes, the functions of the multifunction joystick, and transport and safety instructions are also provided. Operators are offered a visualised recommendation for action and its effect while interacting directly with the machine. The system guides operators step-by-step through the individual scenarios, detects their input commands as well as the machine status and automatically proceeds to the next step.
On top of this, Wirtgen focuses on increasing overall efficiency with the aid of assistance and automation systems and digital process monitoring. The AutoTracTM automated steering system steers the machine automatically on the basis of a previously created reference strip and a predefined overlap of adjacent strips. The Automatic Reverse function enables rapid reversal of the travel direction at the press of a button. With MIX ASSIST, various automated functions can be individually configured and initiated simply by pressing a button. At the same time, operators can set up and save a sequence of working steps as an automated process for later use when needed. Here, the system rearranges the camera images displayed to set a focus on the currently relevant working area. This reduces the operator’s workload and simultaneously improves the productivity of the machine.
Wirtgen Group Performance Tracker Stabilising, in short, WPT Stabilising, generates seamless project documentation. It records all relevant, location-specific construction site parameters and documents them in a detailed field report.
In addition to the WR series, Wirtgen is also showing the WRC 240 X. This machine crushes coarse rocks and stones as found in hand packed stone pavement layers and stony ground and homogeneously mixes the resulting material in a single pass. With a working width of 2,320 mm and a working depth of up to 510 mm, the WRC 240 X can achieve output rates of up to 600 tons per hour.
The heavy-duty crushing and mixing rotor with HT18 toolholders and tools developed especially for the crushing process achieves ideal results in stony ground. The crushing tools have extra-large, extremely impact-resistant carbide cutting edges and holder bases with high-tensile steel wear protection. This ensures high utilisation rates and process reliability in particularly demanding applications. In addition to crushing rocks and stones with an edge-length of up to 300 mm and a uniaxial compressive strength of up to 200 MPa, the machine can also add and mix water and binding agents into the crushed material during the same pass, e.g., for the reconditioning of base layers.
In the case of the new WRS 240 X, an integrated binding agent spreader on the machine enables dust-reduced spreading of binding agents. This makes it particularly suitable for use on freeways, in industrial areas with strict emission standards, and in residential or nature conservation areas. The WRS 240 X has a container with a volume of 5.5 m³ for binding agents such as lime or cement and impresses with outstanding all-terrain mobility. Thanks to this, binding agents can be spread reliably and precisely, especially on soils with poor load-bearing properties in challenging terrain. The WRS 240 X also offers the option of pushing a binding agent silo ahead of the machine. The silo can be continuously filled on stable ground.
With the new WR series models, Wirtgen offers cutting-edge technology for all cold recycling and stabilisation applications. The combination of the innovative operating concept, high performance, and digital assistance systems enables easy handling, highest mixing quality, and low operating costs.
